As the sun cast its warm glow over the village of Konoha, a group of teachers from the Ninja Academy gathered nervously outside the Hokage's office. They exchanged uneasy glances, their expressions a mix of concern and apprehension. Inside, the Third Hokage, Hiruzen Sarutobi, listened intently to their plea regarding Crystal Namikaze, the enigmatic four-year-old sister of the renowned Minato Namikaze.

"Crystal Namikaze is a danger to the other students," one of the teachers began, her voice trembling slightly. "She barely attends classes and spends most of her time outside, seeking out her brother and Sakumo Hatake for training. Her skills far surpass those of her peers, and her demeanor... it's unsettling, to say the least."

Another teacher chimed in, "She's cold, heartless, with a tongue full of poison. We fear what she might become if left unchecked. The Academy is no place for someone like her."

The Third Hokage listened gravely, his expression unreadable. He knew of Crystal's reputation and the concerns surrounding her behavior. But he also understood the potential hidden within her, the raw talent waiting to be honed.

"I see," the Hokage finally spoke, his voice carrying the weight of years of wisdom. "Bring Sakumo Hatake to me. I wish to hear his thoughts on Crystal's abilities."

With a nod, the teachers departed, their footsteps echoing down the corridor. Meanwhile, the Third Hokage sent his trusted Anbu cat to seek out Sakumo Hatake, the White Fang, knowing that his insight would be invaluable in this matter.

Hours passed before Sakumo arrived at the Hokage's office, his presence commanding attention. He spoke passionately about Crystal, praising her skills and potential.

"Crystal learns by merely seeing a hand sign once," Sakumo explained. "Her talent is extraordinary, and her mindset is suited for the rigors of the Anbu. She may be unconventional, but she possesses the strength and cunning to excel."

The Third Hokage listened intently, weighing Sakumo's words carefully. After a moment of contemplation, he made his decision.

"Summon Crystal to the Academy training ground immediately," the Hokage instructed the teachers. "I will meet her there this afternoon."

With a sense of urgency, the teachers set out to find Crystal, their search proving more challenging than anticipated. Eventually, as late afternoon approached, they located her and relayed the Hokage's summons.

Crystal's reaction was a mixture of surprise and curiosity. She had heard whispers of her teachers' concerns, but the prospect of facing the Hokage himself intrigued her.

As Crystal Namikaze made her way back to the academy, her mind was a whirlwind of icy determination and disdain for the world around her. She moved with purpose, her steps deliberate and calculated, much like her personality. The sun was beginning to dip low in the sky, casting long shadows across the village as she finally reached the training ground where the Third Hokage awaited.

Standing there, with his wise eyes peering through the thick frames of his glasses, was the venerable Hiruzen Sarutobi. He looked every bit the embodiment of authority, yet there was a warmth in his gaze that belied his years of experience.

Crystal halted a few paces away, her posture rigid and her gaze unwavering. "You summoned me, Hokage-sama?" she inquired, her voice laced with a hint of disdain.

The Third Hokage regarded her for a moment before speaking, his tone calm but firm. "Indeed, Crystal Namikaze. Your teachers have brought to my attention some concerns regarding your progress at the academy."

Crystal's expression remained impassive, though a flicker of annoyance crossed her features. "Concerns?" she echoed, her voice sharp as a blade. "I fail to see how my progress is any of their concern."

The Hokage nodded slowly, his gaze piercing through her facade. "They believe that you possess skills and abilities far beyond those of your peers," he explained. "Yet, they also express concerns about your attitude and demeanor."

A smirk tugged at the corners of Crystal's lips, though it held no warmth. "Attitude and demeanor?" she scoffed. "What does that matter if I have the skills to back it up?"

The Third Hokage regarded her with a mixture of concern and understanding. "It matters because as a ninja, you must not only possess strength and skill, but also discipline and respect," he replied. "However, words alone are not enough to judge one's worth. That is why I have decided to have a spar with you myself."

Crystal's eyes widened imperceptibly at the Hokage's words, a spark of interest igniting within her cold gaze. "A spar?" she repeated, a hint of excitement creeping into her voice.

The Third Hokage nodded. "Yes. I wish to see firsthand your abilities and judge for myself whether you are ready to graduate from the academy," he declared. "If you prove yourself worthy, you will graduate from the academy and begin your training as a ninja of the Leaf." Sarutobi finishes.

With a curt nod, Crystal accepted the challenge, her heart pounding with anticipation. Today would mark the beginning of her journey to greatness, and nothing would stand in her way.

The training grounds buzzed with excitement as the news of Crystal Namikaze going to have a mock battle with the Third Hokage spread throughout the entire Academy as everyone crowd around to watch this unforgettable battle. Crystal Namikaze, the youngest prodigy of the Namikaze family, prepared for her mock battle against the revered Third Hokage, Hiruzen Sarutobi. Crystal's eyes, cold and unyielding, met Sarutobi's with an intensity that sent a shiver down the spines of those watching.

Sarutobi, recognizing the potential hidden behind Crystal's icy demeanor, approached the battle with a mixture of caution and curiosity. Despite her tender age of four, he knew better than to underestimate her abilities.

With a nod of acknowledgment, the mock battle commenced. Crystal wasted no time, her lightning-fast reflexes allowing her to dart forward with blinding speed. With a flick of her wrist, she unleashed a barrage of wind release jutsu, each strike calculated to perfection. But unlike her brother Minato, Crystal showed no mercy as she pressed her assault relentlessly, her cold-hearted nature driving her forward.

Sarutobi, though taken aback by Crystal's ferocity, met her attacks with a calm and composed demeanor. With a wave of his hand, he countered her wind release jutsu with a powerful burst of fire, the flames dancing in the air like an inferno.

As the battle raged on, Crystal pushed herself to her limits, her lightning release crackling with raw power as she danced around the battlefield. With each strike, she aimed to deliver a devastating blow, her heart as cold as ice.

But even as Crystal fought with all her might, the toll of using high-ranking jutsu at such a young age began to take its toll. As the battle reached its climax, she faltered, her chakra reserves depleted from the intense strain.

With a soft thud, Crystal collapsed to the ground, her breathing labored as she succumbed to chakra exhaustion. The onlookers watched in shock, their admiration for Crystal's skills overshadowed by concern for her well-being.

Among the spectators, Might Guy stared at Crystal with awe, declaring his determination to one day surpass her. His declaration earned laughter from those around him, but Crystal's cold stare sent a shiver down his spine.

As Crystal was carried away to the hospital, Kakashi Hatake watched with a mixture of awe and respect. Despite her young age and limited abilities, Crystal had shown a level of skill and determination that was truly impressive.

And as the sun began to set on the training grounds, Sarutobi couldn't help but feel a sense of pride. Despite her defeat, Crystal had proven herself to be a formidable opponent, her cold-hearted nature tempered by a determination that burned bright. As he watched her being carried away, he couldn't help but think that she would make a fine addition to the ANBU just like Sakumo had suggested.

"Cat, bring me Minato Namikaze right away. It is time to inform him about his sister." Sarutobi ordered. Without saying anything, the anbu code name Cat that was hidden near by body flicker away to search for Minato as ordered while Sarutobi walked away with his hands to his back returning to the office. So much to do, yet he must protect the youngest prodigy from the grasp of Danzo. He has faith that she will surpass the Yellow Flash himself one day.
